This invention relates to an antenna mast structure and moreparticularly to a telescoping or collapsible antenna mast forinstallation on an automotive vehicle, which mast is especially adaptedto be used for television service and repairmen and. salesmen indemonstrating their product.

An object of this invention is to provide an antenna mast for televisionsignals or the like which -may be readily installed on the bumper orrunning board of an automotive vehicle such as a passenger car orpick-up truck so as to enable a salesman to promote and demonstrate thetelevision sets which he may be promoting.

A further object of this invention resides in the provisionor" atelescoping antenna mast which while being rigidly supported on anautomotive Vehicle, may also be collapsed to a relatively small compass.

Still another object of this invention resides in the provision of atelevision mast which has means associated therewith for supporting suchin ground engagement.

A further object of this invention resides in the provision of theclamping means for supporting a transverse rod on the top of anautomotive ve hicle.

Still further objects of the invention reside in the provision of atelescoping antenna mast that is strong, durable, highly efiicient inoperation, simple in construction and manufacture, capable of beingcollapsed to a relatively small compass, and which is relativelyinexpensive to manufacture.

These, together with the various ancillary objects of the inventionwhich will become apparent as the following description proceeds, areattained by this antenna mast, a preferred embodiment of which has beenillustrated in the accompanying drawings, by way of example only,wherein:

Figure 1 is a side elevation a1 view showing the antenna mast comprisingthe present invention in a collapsed position;

Figure 2 is a partial top plan view of the antenna mast as shown inFigure 1;

Figure 3 is a side elevational view showing the antenna mast comprisingthe present invention in an upright position;

Figure 4 is an enlarged elevational view of a portion of the device withparts thereof being shown in section to show other parts in greaterdetail;

Figure 5 is an enlarged vertical sectional view as taken along the line55 in Figure 3;

Figure 6 is an enlarged elevational detail show- 2 ing the supportmembers for holding the upper tubular components of the invention in ahorizontal position when the television antenna mast is collapsed;

Figure '7 is a enlarged sectional view showing the ground engagingmember comprising one element of the present invention, as taken alongthe line 'l--l in Figure 8; and

Figure 8 is an elevational view of the ground engaging member asillustrated in Figure 7.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral 10 generally designates an automotive vehicle having abumper l2 on which the invention is adapted to be secured. Thisinvention includes a sleeve member l4 having ears l6 and I8 extendingtherefrom to which ears there is pivotally connected clamp members 2!)and 22 which are adapted to be bolted together as at 24 so as to embracethe bumper l2.

The sleeve member 14 is provided with a transverse ap-erture in which alocking pin 26 is adapted to be positioned.

Slidably supported within the sleeve [2 and upwardly extending therefromis a lower tubular member 28 adapted to engage the locking pin 25.Suitable stubs 30 are formed on the tubular member 28 in order that thesame may be rotated for a purpose presently seen.

Secured to the lower tubular member 28 is a stop member 32 on whichthere is positioned a collar 34 having a support bracket 36 attachedthereto. Also attached to the collar 34 are cars 40 to which there ispivotally attached one end of a brace bar 42 which is attached to atransverse bar 44 bolted to upwardly extending members 46 and 48 whichare welded or otherwise attached to clamp members 50 and 52, each ofwhich clamp members are provided with an end portion as indicated at 54and 56 which are adapted to embrace and engage the rain gutters of theautomotive vehicle [0. A central member 58 is bolted into clamp-likeengagement as indicated at 60 and 62 with the members 50 and 52.

A coupling member 64 is secured to the top of the tubular member 28 forthreaded engagement by an upper tubular member 66 which has slidablyreceived therein another tubular member 68 which is held by a lockingpin 10 in a vertically extended position. A further tubular member 12 isslidably received within the tubular member 68 and is held in positionby the locking key 14. Swivelly mounted at the top of the tubular member12 is a ring 16 to which guy wires 18 are adapted to be attached foradditionally supporting the television antenna mast,

In order to erect this television antenna, mast on the car or truck itis first necessary to remove the bolts on the ears ll] and on the carsit and then swing the tubular member 28 downwardly. Then the tubularmember 66 is screwed into threaded engagement in the coupling 54 and theguy or guide wires are snapped into the ring it. The antenna is fastenedto the top or section 52 and then the entire assembly is swung up intoposition and the heretofore removed bolts are again positioned in place.It is then possible to climb up the steps 30 and standing on the bracebar 42 it is then possible to raise the telescope or tubular section andposition the locking keys or pins in place. Then, the guy wires may besecured in their desired position to rigidly support the device.

It may be necessary or desirable to permanently afiix the televisionmast to the ground so that the automotive vehicle may be used withoutthe television antenna thereon. To do this, it is merely necessary toremove the pin 2S while supporting the television antenna above thelevel of the ground so that the ground engaging coupling member 83 willbe threadedly engaged on the bottom end of the member 28. Suitableprongs 82 and t l are provided for engagement with the ground. Then, thesleeve is will be allowed to slide up the tubular member 2% or beelsewise removed from the mast leaving the television antenna mast inposition in the ground.

Since from the foregoing the construction and advantages of thistelescoping mast for television or other high frequency antenna isreadily apparent, and further description is believed to be unnecessary.

However, since numerous modifications will readily occur to thoseskilled in the art after a consideration of the foregoing specificationand accompanying drawings, it is not intended to limit the invention tothe precise embodiment shown and described, but all suitablemodifications and equivalents may be readily resorted to which fallwithin the scope of the appended claims.
